WEBVTT YOUR COMPLETE NEWS COVERAGE FOR GREATER LOUISVILLE STARTS RIGHT NOW. RICK: GOOD EVENING, I'M RICK VAN HOOSE. VICKI: I'M VICKI DORTCH. IT'S A FIRE WHICH CAUSED MORE THAN $50 MILLION IN DAMAGE, FIREFIGHTERS SAY THE LARGEST EVER STRUCTURE FIRE IN JEFFERSON COUNTY HISTORY. RICK: NOW, NEARLY FOUR MONTHS AFTER FIRE RIPPED THROUGH GE'S APPLIANCE PARK, FIREFIGHTERS ARE FOR THE FIRST TIME RELEASING DETAILS ON WHAT WENT WRONG. WLKY'S LAUREN ADAMS JOINS US NOW WITH AT THE VERY LATEST. LAUREN: INVESTIGATORS SAY SPRINKLERS WEREN'T WORKING, NEITHER WERE PUMPS OR FIRE HYDRANTS. THEY SAY GE HAD BEEN WARNED ABOUT UPGRADING THEIR EQUIPMENT, BUT FAILED TO DO SO. GE SAYS THAT'S NOT THE CASE, BUT THE LEAD INVESTIGATOR TELLS ME THE COMPANY IS QUOTE, "CHERRY PICKING" THE FACTS TO PROTECT THEIR OWN INTERESTS. IN A MATTER OF MOMENTS ON THE MOMENT -- MORNING OF APRIL 3, THESE GUYS ABOVE GE'S APPLIANCE -- THE SKIES ABOVE GE'S APPLIANCE PARK HAD BEEN FILLED WITH THICK BLACK SMOKE. BELOW, A SIX ALARM FIRE RAGED AT BUILDING SIX. IT WAS AN EMPLOYEE THAT FIRST NOTICED SMOKE, CALLING 911 AT 6:49. JUST TEN MINUTES LATER, AT 6:59, THE FIRST GROUP OF WHAT WILL ULTIMATELY BE HUNDREDS OF FIREFIGHTERS ARRIVES ON SCENE. GE NOW SAYS IT'S "GRATEFUL" THE DEPARTMENT AVOIDED THE SPREAD OF THE FIRE, BUT IN A THREE PAGE STATEMENT RELEASED MONDAY, THE COMPANY SAYS SYSTEM TESTS AND WITNESS REPORTS SHOWED THAT THE AP6 SPRINKLERS WERE IN PROPER WORKING ORDER AND ACTIVATED AT THE TIME OF THE FIRE. THAT, GE SAYS, IS ACCORDING TO CELL PHONE VIDEO TAKEN BY AN EMPLOYEE AND A REPORT BY A SINGLE SECURITY GUARD. THE GE STATEMENT ALSO POINTS TO VIDEO CAPTURED ON A FIREFIGHTER'S HELMET CAM MINUTES LATER AS FURTHER EVIDENCE SPRINKLER SYSTEMS WERE FULLY OPERATIONAL AND THE WATER PRESSURE WAS MORE THAN ENOUGH. THE WATER STREAM REACHES TOP OF 25-FOOT DOUBLE STACKED BOXES, INDICATING AMPLE WATER AND WATER PRESSURE. BUT MAJOR HENRY OTT, THE HEAD OF THE ARSON INVESTIGATION UNIT, TELLS WLKY THERE WAS WATER PRESSURE, BUT ONLY BRIEFLY BEFORE IT WAS LOST. GE SAYS THAT MAKES SENSE. THAT'S WHEN THE SOUTH WALL COLLAPSED. BUT OTT, WHO WILL RELEASE THE FINDINGS OF A 2,600 REPORT -- 2600 PAGE REPORT WEDNESDAY SAYS HIS INVESTIGATION CONTRADICTS WHAT GE BELIEVES. THEY'VE CHERRY PICKED STATEMENTS THAT PROTECT THEIR BEST INTERESTS, AND WE DON'T BELIEVE THEY'RE ACCURATE. TAKE FOR EXAMPLE, THE MATTER OF THE SPRINKLER SYSTEM. WE HAD 13 WITNESSES IN THE BUILDING BEFORE THEIR SECURITY OFFICER EVEN ARRIVED, AND ALL WITNESSES HAVE SAID THERE WAS NO WATER COMING FROM THE SPRINKLERS. TONIGHT MAJOR HENRY OTT SAYS THE CAUSE OF THAT FIRE REMAINS UNDETERMINED. HE SAYS IT IS POSSIBLE RAIN LEAKING INTO THE ROOF CAUSED AN ELECTRICAL SHORT, BUT ONE THING HE IS CERTAIN OF -- IT'S ANTIQUATED EQUIPMENT THAT ACCELERATED THIS FIRE. FOR EXAMPLE, ON APRIL 3, EIGHT PUMPS INSTALLED IN THE 1950'S HAD TO BE MANUALLY STARTED. ULTIMATELY, ONLY ONE WOULD WORK. THE MAJOR POINT OF CONTENTION IN ALL THIS? A SPRINKLER SYSTEM, FIRE OFFICIALS SAY, THAT HAD BEEN INSTALLED IN 1967 -- ONE THE FIRE DEPARTMENT ADVISED GE BACK IN 2013 AND 2014 HAD TO BE
